我是本机反应的新手，并尝试使用此处https://wix.github.io/react-native-navigation/#/docs/Installing?id=android的说明来安装反应导航库。当我完成react-native run-android时的最后步骤之后，我遇到了错误。有人可以帮助我解决以下错误吗？我从最近两天开始就遇到这个问题

答案 0 :(得分：0)
似乎react-native-navigation不支持0.60及更高版本。我将我的本机版本降级为0.58。降级到0.58之后，我遇到了一些新问题，这些问题已经解决，现在react-native-navigation正在为我工作
